2 Claims. l My invention relates to equipment for railroad rolling stockand more particularly for automatic oilers for flanges of wheels ofdiesel 1ocomotives, passenger coaches and the like.

The `object of my invention is to provide a flange oiler adapted to beoperated by the oscillatory movement of a truck relative to a coach bodyor the like, resting on said truck while the coach passes through acurve of the track.

Another object of my invention is to provide a flange oiler of thecharacter indicated above and equipped with two sets of pumps, each setcomprising a cylinder and piston reciprocally arrangedfin the cylinderfor each wheel on one side ofthe truck. y

A further object of my invention is to provide a flange oiler of thecharacter indicated above.A in which only the pumps connected with thewheels rolling on the outer rail of a track curve are operated, whilethe coach passes the curve, and in which these pumps are automaticallyshut oi as soon as the coach enters a straightl stretch of track.

A still further object of my invention is to providena flange oiler ofthe character indicated above "equipped with means for adjusting thepump operating means, so that each pump piston executes a stroke of apredetermined length, and the pump, in consequence, delivers apredetermined amount of oil.

Still: another object of my invention is to provide a flange oiler ofthe character indicated above equipped with a rotary oil distributoradapted to straddle the wheel flange to beL oiled and urged by a springinto permanent contact with the circumferential surface of the wheelange.`z

Other objects of my invention not specifically mentioned may appear inthe following specification describing my invention with reference tothe accompanying drawing illustrating a preferred embodiment of myinvention. y

It is, however, to be understood, that myinveirtion` is not to belimited or restricted to the exact construction and combination of partsdescribed in the specification and shown in the drawing, but that suchchanges and modications can be made,l which fall within the scope of theclaims appended hereto.

In the several iigures of the drawing similar parts are vdesignated bysimilar reference characters and Figure 1 is a View in longitudinalsection of a conventionally illustrated wheel truck of a rail- Way cartogether with a portion of the overlying 2 car body, showing theapplication of a flange oiler, constructed in accordance with thepresent invention.

Figure 2 is a view partly in vertical section and partly in elevation ofthe oil reservoir and the mechanism within the same.

Figure 3 is a vertical section taken substantially on the line 3-3 ofFigure 2 and including, in elevation, the operative coupling between theoiler and the bottom of the car body.

Figure 4 is a view partly in elevation and partly in section of thewheel flange contacting element the section being thru the distributorapproximately on the line 4-4 of Figure 5.

Figure 5 is a view partly in elevation and partly in section of theilange engaging wheel.

The flange oiler forming the subject matter of my invention comprises asubstantially circular oil reservoir a consisting of a body portion l0and a top cover plate Il adapted to be secured to the body portion bymeans of a plurality of bolts I3 or the like extending through holesprovided in the cover plate Il and threadedly engaging a flange 9 formedon the top edge of the circumferential wall of the body portion I0 andextending inwardly therefrom at a right angle.

An outwardly extending circumferential ange I4 is formed at theloweredge of the body portion I0 and is provided with a plurality ofholes l5 therein, permitting screws I6 to extend therethrough and toengage the truck c.

The numeral I1 designates an elongate pump block having a substantiallyrectangular Vertical cross section and a substantially rectangularlongitudinal vertical section, which block is secured to the bottom andinside of the body portion ID by means of a plurality of screws I8 ex'tending through holes provided in a surrounding flange I9 formed on andextending outwardly from the bott-om corner of the pump block l'l, sothat the bottom of the pump block is supported at a distance above thebottom of the body portion l0, when the pump block is placed intoworking position in said body as shown in Figure 3.

Adjacent to one end of the pump block an upwardly extending bearingblock 20 is formed and is provided with a downwardly extending blindbore 2|, on the bottom of which a ball thrust bearing 22 or the like ismounted.

Centrally of the pump block part next to said blind bore, a bearing bore23 extends downwardly through said block and at each side of saidbearing bore 23 two cylinder bores 24 and 25 respectively extenddownwardly through the block.

The lower end of the central bearing bore 23 opens through the bottom ofthe block and is tapped and a screw plug 2S is adapted to be screwedinto the tapped end of the bearing bore to close the same.

A helical spring 2l is inserted in the bearing bore 23 and rests on thescrew plug 26. On the upper end of the helical spring 27 a ball thrustbearing 28 or the like is arranged to support a cam shaft 2t extendingupwardly through the bearing bore 23 into the oil reservoir a.

The lower end of each cylinder bore 24 and 25 opens through the bottomof the block and is tapped and a screw plug 3! is screwed into each ofthese tapped cylinder bore ends.

Each cylinder screw plug 30 is provided with a central hole 3i, thelower end of which tapers downwardly to form a valve seat for a ballcheck valve 32 arranged in said hole.

In the upper end of each hole 3l, a pair of diametrically inwardlyextending prongs 33 may be provided permitting free play of the ballvalve but preventing it from escaping from the hole in the cylinderscrew plug.

On top of each of these cylinder screw plugs, a helical spring 3:2 isarranged urging a piston 35 upwardly, which is reciprocally mounted inthe corresponding cylinder bore 24 or 25.

The top of the upper end of each piston 35 is provided with aSemi-globular hollow 35 adapted to receive a hardened steel ball 3ltherein.

The top end of each piston 35 is threaded and a retainer ring 38 isadapted to be screwed onto each piston to keep the corresponding bearingball 31 in position while permitting rotary movement of said ball.

A drive shaft 39 is rotatably located in the blind bore 2|, rests on theball thrust bearing 22, and extends upwardly through a brass bushing i5extending through and secured in a hole 4l provided in the cover plateIi coaxially with the blind bore 2i in the pump block Il, so that thebrass bushing i5 serves as bearing for the drive shaft`39.

A comparatively large spur gear 42 is rigidly mounted on the drive shaft39 justl above the top of the bearing block 2i! of the pump block Il.

A pinion 6.3 is rigidly mounted on the cam shaft 29 and meshes with thespur gear 2.

The pinion i3 is considerably wider than the spur gear 42 for a purposeto be described hereinafter.

Underneath the pinion 43 a cam disk b is rigidly mounted on the camshaft 29.

Coaxially with the bearing bore 23 a tapped hole 44 is provided in thetop cover plate Il and an outwardly threaded bearing bushing 45 engagessaid threaded hole and extends inwardly into the oil reservoir il).

A ring ball thrust bearing 45 surrounds the cam shaft 29 and rests onthe upper end surface of the pinion d3.

The upper end of the cam shaft 2 extends into the bearing bushing i5 andis rotatable therein.

lThe bearing bushing is provided on its upper end with a hexagonal headIt', and a jam nut il is mounted on said bearing bushing outside of theoil reservoir a.

The cam disk b has a thin ilat portion t8 adapted to engage normally thebearing balls 3l of the pistons 35.

One portion i9 of the cam disk b is heavier or thicker than the mainportion 48 and is adapted to engage the bearing balls 31 of the pistons35 in the two cylinders 24 or in the cylinders 25 under conditions to bedescribed later and to force these pistons downwardly in theircylinders.

On the uppermost end oi the drive shaft 39, a crank arm 5B is secured bymeans of a corrugated clamp 5I formed on said crank arm and adapted tobe operated by a clamp bolt 52.

A hook shaped bracket 53 is bolted onto the bottom of the coach body 54and a connecting rod 55 is attached with one of its ends to said bracketby means of a ball joint 55, and with its other end by means of a secondball jointl 5l to the free end of the crank arm 5b.

Each cylinder 2li and 25 is equipped adjacent to its lower end with anoutlet nipple 58. A ball check valve 59 is mounted on each nipple 58permitting liquid to flow out of the cylinder under pressure eventuallyexerted by the cylinder but preventing such passage of liquid undernormal conditions.

A pipe is secured to each ball check valve 59 and leads through thecircumferential Wall of the oil reservoir.

Leakage of oil from the reservoir throughthe several openings in thereservoir is prevented by packing the pipes passing through said openingin any preferred conventional manner.

A clamp bracket 6l is adjustably secured to each side of the brake post62 provided on the truck c for each wheel d in any conventional manner.A pair of bracket plates 53 is secured to each clamp bracket 5| adjacentto its upper end, and the plates of each pair are spaced from each otherand are provided with coaxial holes 64. A bracket pin G5 is supported inthese holes and extends between each pair of bracket plates, to whicheach pinis secured.

On each bracket pin a pair ci' distributor arms E6 is pivotally mounted,and in coaxial holes 6l provided in the distributor arms adjacent tother' free ends a short shaft 58 is located.

An oil distributor e is shaped similar to a spool and is provided withtwo circular end flanges 69 and a body 78. The oil distributor is formedso that the ange 'H of the coach wheel d its into the space between thetwo end flanges 469 of the distributor e, which is provided with acentral bore 12 having a counterbore 'I3 on each of its ends.

The outer race of a ball bearing unit 74 is arranged in the counterbore13 and is secured therein.

Through each bore 12 one of the shafts `68 extends and the inner racesof the ball bearings 'M are secured to the said shafts 63, which arelocated as stated above, in the holes 61 in the free ends of thedistributor arms 66.

Each shaft extends beyond the corresponding oil distributor arms 66 andthe end of each shaft is threaded. Jam nuts 15 on these threaded endsengaging the corresponding distributor arm `65 prevent rotary movementof said shaft.

A plurality of distributing pockets 'I6 is provided in the inner face ofthe outer endflange S9 of each distributor e.

On each distributor arm 55 which is adjacent to the inner flange 69, anoil delivery pipe 'Il is mounted by meansvof a nozzle clamp 18 of anypreferred conventional construction.

On the outer end of each delivery pipe 'Il a nozzle 'IQ is secured andbetween each nozzle and corresponding'delivery pipe a ball check valve30 is provided, adapted to close the outlet of said pipe automaticallyunless pressure in the opens the valve.

On the inner end of each delivery pipe 11 a hose 8| is attached, theother end of which connects with one of the pipes 60 leading from one ofthe cylinders 24 or 25.

The end of the nozzle 19 is arranged at the inner side of the outer endiiange 69 of one of the oil distributors e, in a position where oilejected from the nozzle will enter the pockets 'I6 in the distributorand will oil the ange 7| of the coach wheel d.

To keep the distributor e in contact with the wheel d a g-uide bracket82 extends from'the clamp bracket 6| and is provided adjacent its freeend with a vertical hole 83, through which a bolt 84 or the like extendsupwardly between each pair of distributor arms 66. 1

A transverse block 85 is arranged across Veach pair of these arms 66 andis provided with a vertical hole 86 permitting the bolt 84 to extendtherethrough. The upper portion of said bolt is surrounded by a helicalspring 81 abutting with its lower end on the transverse block 85 andwith its upper end on a nut 88 mounted adjustably on thefupper end ofthe bolt 84, so that the Apressure of the helical spring 81 mayberegulated by said nut.

The above description shows clearly that the automatic ilange oileraccording to my invention operates as follows: y

The" cover plate is provided with a tapped hole 89, through which oilmay be introduced into the reservoir a. The hole 89 is normallyclosedjby a screw plug 99.

A drain opening 9| is provided in the circumferential wall l of thereservoir a adjacent the bottom thereof. This drain opening is tappedand is'normally closed by a second screw plug 92.

To observe the amount of oil contained in the reservoir a glass gage 93'of well known construction is provided on and communicates with thereservoir a. l

pipe

As long as the truck c supporting the coach' body 54 travels on astraight track, so that the coach body and the truck extend parallel toeach other,fall pistons 35 are arranged in raised position in thecylinder bores 24 and 25 under the upward pressure of the helicalsprings 34, since the cam disk b is arranged so that the thin flatportion 48 is in engagement with the balls 31 on top of the pistons 35.

When the truck c enters a curve of the track it is pscillated relativeto the coach body 54, rotating the spur gear 42 by means of the crankarm 50. Since the pinion 43 is in mesh with the spur gear 42, the camshaft 29 is rotated and the cam disk b is rotated therewith forcing` thepistons 135 on the outside of the track'` curve downwardly, expellingthe oil in the correspond- .v ing cylinders through the pipes 60, thehoses 8|,

pipes y1`| and the nozzles 19 on to the oil distributors e. The oilenters the pockets 16 in said distributors which are rotated by means offriction by the coach wheels d, and is fed therefrom to and oils theflanges of said wheels.

As soon as the truck again enters a straight stretch of track, it isoscillated into a position parallel to the coach body, rotating the camdisk into position permitting the? helical springs 34 to force thepistons upwardly in their cylinders, thereby sucking oil from thereservoir into the cylinders.

Having described my invention I claim as new and desire to secure byLetters Patent:
